• We have applied a dynamical model for polyelectrolyte solutions proposed in I of the present series to derive the polymer viscosity. In the infinite dilution limit, the stationary intrinsic viscosity increases from the ordinary value for the non-electrolytic solutions to infinity. Its increase is $(1-\tau)^{-2}$ for small $\tau$ which is the average of the charge distribution $\{\tau_{\alpha i}\}$ related to the degree of electrolytic dissociation and $0{\le}\tau{\le}1$. From the $\omega$-dependence of the intrinsic viscosity, it is found that a new "internal" viscosity is induced. Further, we calculate the concentration dependence of the reduced viscosity in rather dilute solution. There, the similar enhancement is also found. These are caused by the rapid response without delay of the charged fluid to the point charges attached to the polymers.
